Exhibit show.php Not Responding

Greetings. This is doubtless a beginner's question, but apparently I'm stumped. I want to move the class exhibit-page-nav from where it sits into another div that I've made, and is located in the common/header.php file. I'm using the Default/Thanks Roy theme, and out of the box, it did NOT have an exhibits directory, so I copied one from another theme so that I could edit the exhibits/show.php document. Sadly, no changes I make to the new exhibits/show.php file appear on the page I'm editing, which has the url /exhibits/show/xyz. I can't seem to figure out where the content for this page is being drawn from. What am I not understanding?

Starting at the theme's root directory, the file you should be editing should be called:

exhibit-builder/exhibits/show.php

Is this the name and path of the file you're editing?

Thanks for the reply John. Unfortunately, there isn't an exhibit-builder directory in the root. There is an ExhibitBuilder directory in the plugins directory, but the show.php for it is buried here: plugins\ExhibitBuilder\views\public\exhibits and isn't at all what I was looking for. If the exhibit-builder directory is supposed to be in the root, wouldn't it have been included in the original download of Omeka? I know I haven't deleted it. Ideas?

Well, you said you copied "an exhibits directory" from another theme.

In a theme, the view file for an ExhibitBuilder exhibit show page would go at

exhibit-builder/exhibits/show.php

That's where any other themes that override that view would have that file.

As for your question about the "root," by "the theme's root directory" I meant themes/your-theme, not the top-level Omeka directory.

Right, I know you meant the theme root. My theme root contains the following directories: Collections, common, css, exhibits (the one I copied in), images, items. That's it. No exhibit-builder folder. Never had it, so I just copied one in from another theme and now I have something to work with - thanks!
